MSBuild troubleshooting

This is the entry skill. Choose troubleshooting, performance, or authoring review, then read only the relevant local references. The references retain the content and identities of the original MSBuild skills, with correctness fixes; they are not separate skills to activate.

Start with the task and evidence

For tasks that need a checkout, discover the relevant project/solution, shared build files, SDK selection, and repository build instructions in the current workspace. Preserve the original command, working directory, configuration, target framework, runtime identifier, global properties, and target. Ask only for consequential information that cannot be discovered.

An existing .binlog can be the only available artifact. Analyze it before requesting a new build; paths inside it do not prove a checkout exists locally. For a self-contained static review or advisory question, use the supplied XML and relevant references; do not require a checkout, restore, build, or binlog.
